Protect Your Investment!

The number one cause of diesel injector failure is fuel quality. Stanadyne Performance Formula® protects your diesel engine and improves engine performance. It is approved by major vehicle manufacturers including Ford, GM, Navistar, Deere, Caterpillar, VW, AM General, and Volvo Penta. The detergents and cetane improvers in Performance Formula will help restore fuel economy, increase horsepower, and increase torque.  In the years since common rail fuel systems were designed and introduced, fuel formulas have changed significantly. The most notable change has been removing sulfur which previously acted as a natural lubricant for injectors and pumps.  Stanadyne Performance Formula® helps restore these lubricating properties. We recommend running it in every tank to ensure maximum performance and life expectancy of fuel system components.
